The Food and Drug Administration on Monday approved the country’s first drug derived from marijuana, a medication that treats two rare and devastating forms of epilepsy.
The drug, GW Pharmaceuticals’ Epidiolex, is made of cannabidiol, or CBD, a component of marijuana that does not give users a high. It is given as an oil, and in clinical trials, it was shown to reduce the number of seizures by about 40 percent in patients with Dravet or Lennox-Gastaut syndromes.
“This approval serves as a reminder that advancing sound development programs that properly evaluate active ingredients contained in marijuana can lead to important medical therapies,” FDA Commissioner Scott Gottlieb said in a statement. “And, the FDA is committed to this kind of careful scientific research and drug development.”
The FDA’s decision was expected. FDA officials had indicated they supported approving Epidiolex, and an advisory panel had unanimously recommended it get the green light. There was some concern about the drug’s effects on the liver, but experts have said this risk could be addressed by doctors as they monitor their patients during treatment.
